IN CASE OF DIFFICULT Y

to enter into memor y. When the
call is ended, press 

,

and a memory button.

• If someone lifts an extension

phone while you are storing num-
bers in memory, programming
might be interrupted. Make sure
all extensions are on hook while
storing numbers in memory.

• You might not hear the confirma-

tion beep if the RECEIVER
(handset) volume is set too low, or
if you are in a noisy location.

• If the number is more than 24 

digits long, make sure you follow
the directions for “Dialing Long
Numbers.”

• Do not put the phone on Hold

while storing numbers.

Problems With Line Status Lights
• Make sure all plugs are connected

properly. Inspect the line cord
connections at the modular jack
and at the telephone . Also inspect
the coiled handset cord connections
at both ends.

• Try replacing old bat t e ries. See

“ B at t e ri e s ” in the Installation section.

• Make sure the batteries are

correctly installed, and that the
battery contact surfaces and 
battery case are clean.

• If only one telephone line is 

connected, make sure that only the
batteries for that line (as labeled
on the battery compartment) are
installed.

Telephone Does Not Ring
• Make sure the RINGER switch

is set in the LO or HI position.

• If there are several other 

telephones on the same line, try
disconnecting some of the other
telephones. Having too many
telephones connected can also 
create problems such as low ringer
volume, or impaired sound quality
during calls.
